This CL also removes JSTypedArray and JSDataView static visitor Ids because the visiting logic is the same as for ordinary JSObject.

1) Body descriptors moved to their own header files.
2) Missing body descriptors added.
3) Template versions of HeapObject::Iterate*() methods added.
4) Body descriptors support new kind of queries: IsValidSlot(offset) which can be used for invalid slots filtering.

This is a first step towards virtual and static visitors unification and support in-object properties in built-in (sub-)classes.

Drive-by: remove unnecessary includes.

This moves scavenging functionality into a separate component so that
neither the scavenger nor objects-visiting need to be exposed outside
the heap.
